1230pm EST. Press conference. Scotland Yard executed six warrants in the West Yorkshire area, including three of the four suspected terrorist bombers. All four arrived by train in London on the morning of 7/7. Video shows the group meeting at King’s Cross station.

Three of the men lived in Leeds and the immediate fear is that members of a terrorist cell linked to the city are planning further strikes. The mastermind behind the attacks and the bombmaker are both still thought to be at large.

The man who planted the bomb at Edgware Road was named last night as Mohammed Sidique Khan, 30, the married father of an eight-month-old baby, who is believed to have come from the Leeds area.

Two other terrorists were Hasib Hussain, 19, who bombed the bus in Tavistock Square, of Colenso Mount, Leeds, and Shehzad Tanweer, 22, the Aldgate bomber, who lived at Colwyn Road, Leeds.

Police are still trying to identify the fourth, whose remains are believed to be in the bombed Tube train carriage on the Piccadilly Line. It is thought that he comes from Luton.
